Earlier today, my wife gave me three textbooks to sell on half.com. Three hours later, this one had sold — $40 without barely lifting a finger. Of course, I priced it about $10 less than everyone else, but I like to move my merchandise. The Internet is wonderful thing.

If you haven’t purchased anything through half.com, you should. Usually somebody in the world is willing to sell you the exact book you want for about three bucks plus postal shipping.
